table or .Slpecification Referring to Fig. 1, 28 is the pinning device proper. The device 20 consists of a base 2! and comprises a tapered portion 22 and a. horizontal portion 23. A pair of side frames 25 and 25 are attached to each side of the base 2!, a shaft 25 (see Figs. 2 and 3) is held in bearings 26a which are located in the side frames 24 and A pair of hinging segment shaped plates 21 and 28 are attached to both ends of the shaft 3 25. The segment plates 2'? and 28 are attached to both ends 35 and 3! of the shield or shutter plate 25. An elongated angle bar 32 is fastened to the shield 29 as shown in Figs. 2, 3, '7 and 8. A pair of hingeably mounted U-shaped frames 53; and 3 3 are hingeably attached to the side frames 25 and 25 as 35 and 36 by screws 37. The elongated angle bar 32 is used to align the bill sheets B upon the base 2i. For this purpose the top margins of the bill sheet is placed so as to contact the elongated angle bar 32 while the sheet is held upon the base 2| by hand. The elongated pin bar or pressure bar 38 is attached at both ends 39 and All to the hingeably mounted frames 33 and 54. A number of openings M are located lengthwise upon the bar 38. A pair of gear segments 42 and 43 are attached to the lower portion of each of the side frames 33 and 34 respectively. The gear segments 42 and 43 are in mesh with another pair of gear segments 44 and 45 which are attached to both ends of the shaft 25. A pinstrip bar or holder 48, which comprises an elongated flat plate ll and an L- shaped bar 58, is removably attached to the de vice proper upon the locating studs 49. The

locating studs 59 are attached to both ends of the base 2| (see Fig. 4) The flat plate 41 of the pinstrip 5'5 carries a number of upright pins 50. The L-shaped bar 38 has an inverted U-shaped portion 5| which is so arranged as to cover the pins 55, while a'number of coil springs 52 (see Fig. 4) hold the .L-shaped hinging bar 48. under tension in the position as shown in Figs. 2 and 3. The operation of the pinstrip holder 46 will be described herewith.

A pair of holder members 52a are hingedly attached to the extensions 53 on both side frames 24 and 25'by th screws 54. The holder members 52a are formed at one end into hook-like portions 55 to facilitate the holding in place of the L- shaped hinging bar 45 when the L-shaped bar 48 is in upright open position as shown in Fig. 8. The opposite ends 56 of the members 52a are used by the operator when it is required to release the L-shaped hinging bar 48. To that purpose they are depressed by the operator simultaneously at both ends of the pinning device.

To facilitate the locking in position of the pin bar 38, an arm 51 is hingedly attached to the shaft 26. A curved extension 58 of the arm 51 has a downwardly extending member 59 which engages the L-shaped bar 48 when said bar is hinged into the upright or open position as shown in Fig. 8. The arm 51 has a groove 60 which engages a pin 5!. The extending member 59 is flat upon its left side and will contact the L-shaped bar 48 when said bar will be hinged in the position shown in Fig. 8. Being that Fig. 8 is a sectional view and Fig. 7 an outside side view of the device the curved extension 58 and the arm 51 have been omitted in Fig. 8. The operation of the L-shaped bar 48 upon the extend ing member 59 will facilitate the hinging of the arm 57 to release the bar 38. normally in operative position due to the locking action of the pin 6| which is located upon the side frame 33 of the bar 38 and rides or engages the groove 60 of the arm 51. The operation of hinging the arm 51 by the bar 48 disengages pin (if from the groove 60 and releases the bar 38 for operation by the attendant. The pin 6| is located upon the side frame 33 and engages the groove 60 of the arm 51 when the device is not operated. A finger tip 62 is located on the arm 51. The finger tip 62 is used when it is desired to disengage the arm 51 from the pin 6| when operating the device.

Referring to the summary or aligning board 63 shown in the Figs. 10 to 15 it consists of a flat table top 64 which has four downwardly extending sides 65, 66, 61 and 68. An operating shaft 69 turns into bearing bushings 15 and H which are attached to the sides 66 and 61 of the table top 64. A secondary shaft 72 is made to rotate into bearing members 73 and M which are also attached to the sides 66 and 61 of the table top 64. The bearing members 13 and 14 have elongated openings 15 so that while the secondary shaft 12 is able to rotate it can also he slid in the direction indicated by the arrow A. A pair of bushings 16 are located over the shaft 12 and are attached to the tension springs 71 which are in turn attached to U -shaped portions 18 of the tension shaft 19. Both ends of the shaft 19 extend beyond the sides 66 and 61 of the table top 64 and are attached to the handles 8|. The operation of the tension shaft 19 will be described hereinafter.

A pair of L-shaped guide members 82 are attached to the sides 66 and 61 of the table top 64 The bar 38 is held in such a manner as to provide a slot or opening 83 between said sides 66 and 61 and the 'L-shaped member 82. Within both of the slots 83 there is located a pair of angle-shaped members 84 and 85 which are connected to each other through connecting bar 86 and 81. Upon the upper portion 82a of the angle members 84 and 85 there are attached a set of studs 88 which serve to receive and hold in position an aligning ruler or bar 89. The chains 98 and 9| for sliding the aligning ruler 89 are placed over sprockets 92 which are attached to the operating shaft 69 and over the sprockets 93 which are attached over the secondary shaft 12. The ends 94 and 95 of the chains 98 and 9| are attached to the connecting bars 86 and 81. Both sides 66 and 61 of the table top 64 have an L-shaped slot 96 and an elongated slotted 91. The utility of the slots 96 and 91 will be described hereinafter. Numerals 98 and 99 designate the position of the chains I88 and I8I, one chain I88 located on the left side of the pinning device and the other chain I8I being located on the right side of the device.

Referring to Fig. 18 it is showing a combination of an aligning board or line-up table similar to one 63 shown in Figs. 10, 11 and 17 with the sole difference that it is directly attached to the bill pinning device 28 shown in Figs. 1, 2 and 3 instead of being removable. Referring the aligning board 64 shown in Figs. 10, 11, 16 and 17 the slot 96 is placed over a pin 96a (one of each attached to the right frame 24 and left frame 25 of the pinning device 28) to facilitate the conjoining of the aligning board 64 to the frames 24 and 25 of the pinning device or holder 28.

The other slot 91 is shoved under the thumbnut 91a which is made tight to hold the board 64 to the pinning holder 28. When it is desired to disconnect the aligning board 64 from the holder 28, the thumbnut 91a is loosened and the board 64 is detached from the holder by sliding it off the pins 98a.

Note that the aligning board 63 as shown in Figs. 18, 11, 16 and 17 has a pair of L-shaped slots 96 on either one of its sides 82. It also has a pairof elongated slots 91. These L-shaped and elongated slots allow for the removal of the aligning table 63 from the pinning device 28. In the case of Figs. 18 and 19 the aligning board 63 is built into the bill pinning device 28 and comprises one unit instead of two. The aligning ruler 89a is in this case operated manually by pushing directly upon it.

In the case of the aligning board as shown in Figs. 20 and 21 the aligning ruler 89b is operated through chains 98 and 9| and knobs 6911 similar to the ones shown in Figs. 10, 11 and 17. Here also the aligning board 63 and the bill pinning device 28 are built into one device and are not removable. The chains 98 and 9| are not attached to the connecting bars 86 and 81 as shown in Figs. and 11 but to a pair of studs 86a and 81a attached to the angle shaped members 84a and 85a on each side 82 of the aligning board 63. The chains 98 and 9| run over sprocket wheels 92 and 93.

An important feature of this invention is that it allows an operator of the device in an easy and simple way to disconnect the aligning board 63 from the pinning device 28 and it makes possible the sale and distribution of the pinning device in combination with an aligning board or separately.

Incertain cases it is necessary to operate the pinning device 28 by foot as to allow the operator the free use of hands. To this purpose a foot pedal operated device 4 (see Fig. 28) is attached to a desk or table D through a pair of knurled tightening thumb nuts H5. The device I I4 consists of a pair of U-shaped channel members H6 and H1. A hinge H8 is attached to the end N9 of the channel H6 and to the end I28 of the channel II1 while a double fulcrum arm I2I is hingedly secured upon the pin I22 of the hinge H8. The thumb screws II5 are threaded into an angle member I23 that is secured to the upper end I24 of the channel H4. The lower part of the screws I I5 is held in a flat plate I25, while a secondary angle member I28 is attached to the upper end I24 of the channel 4 and below the angle member I23. T0 attach the foot pedal device to the top T of the desk D, the angle member I26 is shoved under the top T of the desk D and then the plate I25 is clamped tight above the top T.

Another double fulcrum arm I21 is hingedly attached at I28. The fulcrum arm I2! is connected to the fulcrum arm I 2| by a connecting link I29, which is under the tension of the spring I38, and to a link I32 which is made to slide in a bearing I32. The bearing I32 is attached to the channel In at I33 and the end I34 of the link I3I contacts the pedal I35 at I36. To operate the pinning device 28, the long extension |21a of the double fulcrum arm I21 is attached to a link I31 which in turn contacts the edge 38a of the bar 38 through a 'pivotally mounted bracket I38. A pair of shelves |I3 are attached to either side of the base 63 (see Fig. 26) to help support the pinning device 28 when it is attached to the base 63 through the screwsI89 having a threaded portion I|8 fitted into an opening III of the shelf II3.

As it is important to have the pinning device 28 and the foot pedal device 'I I4 attached in correct relation to each other, a'pairof holding arms I39 is used as spacer links between the device 28 and the pedal device 4. The holding arms I39 are hingeably secured to the channel H6 at I48. When it is required to have the pinning device operated by the foot pedal device, the arms I39 are inserted into an opening I4I located at the rear of the pinning device 28. The arms I39 and into hook like portions I42'which engage the edges I4Ia of the opening MI and thus hold the device 28 in place until removed from the foot pedal device by the operator. The lower end II9 of the channel II6 has an opening to allow the passage of the rod I29. The end I34 of the push rod I3I contacts the fulcrum I36 that is operated bythe footpedal I35. The arms I39 have cutouts I42 of L-shaped formation to hook within the slot I4I (see Figs. 30 and 31).

When the device 4 is removed from the desk D, it is collapsed together by hinging the channels 6 and H1 upon the hinge H8. The link I31, arm I39 and foot pedal I35 are hinged around and placed within the confines provided by the sides of the channel H6 and Ill. The foot pedal device 4 operates the pinning device 28 when the operator depresses the foot pedal I 35.

Operation When it is required to operate the device, the pinstrip holder 46 is placed upon the horizontal portion 23 of the device 2| and is attached to the studs 49,the L-shaped bar 48 is then hinged rearwardly as shown in Fig. 8 and is held in position by the hooked holding members 52a. .In

this position the pins 59 of the pinstrip holder 46 are exposed and ready to receive the bill sheets. To attach the bill sheets B upon the pins 59 the bills are placed upon the tapered portions 22 of the base 2| as shown in dotted lines in Figs. 2, 3 and in solid lines in Fig. 7, then the upper end B of the bill sheets B are shoved against the angle bar 92 of the shutter 29 to assure correct alignment of the bill sheets upon the device, This done, the operator hinges the pinning bar 38 in the direction indicated by the arrow C untilthe pinning bar 38 reaches the position as shown in Fig. 8. v

It can be seen that the shutter 29 is attached to the segment-shaped plates 39 and 3| which in turn are attached to the segment gears 43. Also the pinning bar 38 is attached to the U-shaped frames 33 and 34 which have a pair of segment gears 45 attached thereto and which are in mesh with the segment gears 43.

When the pinning bar 38 is hinged in the direction shown by the arrow C, the shutter 29 is hinged in the opposite direction indicated by.

the arrow D and exposes the pins 50 of the pinstrip 46 allowing the bill sheets B to be pressed upon the pins 59.

This operation is repeated every time a new bill sheet is pinned upon the pinstrip holder 46 until it has filled up its desired length. Then it is removed and a new pinstrip holder is placed upon the device.

To protect the operator from injuring himself from the pins 59 the shutter 29 is always held in position over the pinstrip holder 46 when the L-shaped bar 48 is held open as shown in Fig. 8.

The pinstrip holder 46 cannot be removed from the device until the L-shaped bar 48 is in its original closed position as shown in Figs. 2 and 3 and covering the pins 59 by its inverted U- shaped portion In this position, the looking arm 51 engages the pin 6] which is attached to the frame 33 of the pinning bar 38 within the groove 60 and locks the device in the position as shown in Fig. 7, leaving enough space in between the lower part of the shutter 29 and the pinstrip 45 to facilitate the easy removal of the pinstrip from the studs 49. When a new pinstrip is placed upon the device and the L-shaped bar 48 is hinged backwards, it will engage the downwardly extending portion 59 of the arm 51 and move it in the direction indicated by the arrow E. This action will disengage the pin 6i from the groove 69 to unlock the device for further operation.

Figs. to illustrate a removable summary or aligning board to beused in conjunction with the bill sheet pinning device shown in Figs. 1 to 9. Y

The aligning board is used in cases where it is necessary to align a number of bill sheets at the same time in series. The bills for that purpose are placed in staggering formation one upon the other as shown in Fig. 9, their lower edges resting against the aligning ruler 89. The ruler 89 is arranged to slide upon the table top 64 of the aligning board.

When it is required to adjust the position of the ruler 99 the knobs 69a are used. The knobs 69a turn the operating shaft 69 which in turn rotates the shaft 12 throughthe sprockets 92 and the link chains 99and 9|.

The ends 94 and .95 of the chains 90 and 9! are attached to theconnecting bar 86 which connects both angle members 84 and 85 together. The ruler-69 has apertures on either end'and is attached to the studs 88 which are located upon the angle members 84 and 85.

When it is necessary to move the ruler 69 fast upon the aligning board, the knobs 69a are dispensed with and the ruler 69 is slid by hand. To remove the pressure of the springs ll from the chains 99 and 9|, the handles 8! are turned clockwise. This operation will rotate the U- shaped portions 18 of the tension shafts 79 and allow the spring tension of the springs 77 to slacken. After the ruler 69 is removed from its position and is moved. the handles 8| are rotated back in their original position and the knobs 62a are used for finer ruler adjustment.
